Beitknown that I, Ciiaizmis `Pizrx-ziisiza,

"My .invention `.relates to .fountain pens and 'has especial referenceyto .that type in `which the pen isprovided with mechanism whereby .afresh supply of -ink :may be dra'wrr into thereservoir, such articlesbeing y commonly known yas self-filling pens.

.'Ifhe chief r'ibjectsv of the `ii'nprovements `wlnchform-t-he 4subjectmatter of this application .for atent 'are:-to provide a self filling'fountain r pen -thaty will be `simple in construction, effective in theoperation `of charging the reservoir with a 'freshjsup- `ply of ink,

ingdevices will be durable, easily understood, and `convenient tooperate.

I respectively, of the barrel; Figi is a fragcal section of the fillingpiston,

f plication, the various sprin `Furtherobjects fof the invention,referred to more :in detail, are z-to furnish a `positive lmechanismyforforcing the ink into the Areservoir by atmospheric pressure, to4provide a `safety clip function of serving as the operating lever forthe filling member, andto .produce a fountain pen having `an effectivefeed that will insure that the proper amount of ink is at all timessupplied to the pen nib.

I accomplish the desired objects by means off the devices illustrated inthe accompanyin drawing, which forms a part of 'this apdetails ofconstruction being disclosed in the following views lFigure 1 is asideelevation of the coniplete instrument; Fig. 2 is a verticallongitudinal section; Fig. v3 isa side elevation of the cap, with thesafety clip and sprin 'removed; Fig. 4 is 'a front elevation o thesafety clip; Figs. 5 and `6 are fragmentary views showing the upper andlower ends,

Referring c 11 indicates a cylindrical barthe numeral rel, lopen at thetop and having its lower and so constructed that the lill-` having theadditional The said clip is normally will expand so as thus retain thespring end 12' contracted andprovided with :a slot 13 `for the insertionof .a pen-114. -Tlieaipper lend 15 ofthe pen'is `reduced'-formingshoulders 16 4which enga'gelt'lie marginsof vthe said slot 13, thusformino' stops to properly locate `the member .relatively to thevfeeding mechanism. The 'feeding :parts comprise a beak 17 )which 'is areducedex-y tension of the barrel walls, fandvisfurnished upon one sidewith `a latlface 18A whichis a jacent the slot 13`andwis'pi'ovidediwitha groove 19. This e groove communicates'fat oneend with the bore 20 of the ybari'l,-ftlie lower end terminatingfshortof the endfmargin 'of said face.18,as^shown 'inFigs Gand 7.4 The upperopen end of the barrel is normally closed by a cap 21, whichtelescopesv,over tli'e ysaid open :end andvex-tends downward to-a sutiicientdistance to afford a "iirm connection when tliusengaged, the cap beingreadil removable 7for the purpose'iof 'til ing the re A20 with ink.

fTlie upper end `22 fofwtlie cap isfsolid 'except for a slot 23 ii'-which is '-insertedthe u per end 24 of a clamping lever or safety clipA25, which normall cap `and barrel-in 'the ie ative position shown inFigs. 1 and 2. This clip or `lever coniprises aiiat metal strip which isreinforced along the median line lof the, outersurface flattened endQ/l,the latter being secured in the slot 23 by a pivot pin 27. The lower endof the clip terminates in an outwardly turned hoop 28 which lies inclose 'proximity to the outer surfacey of the barrel, as 'indicated at29, and serves vto engagethe margin of a pocket or other convenientportion of a garment for the lpurpose of preventng the instrument frombecominglost, a su cient resiliency beino' provided by the'vmetal clipto facilitate this clamping function.

tion shown by means .pf a U-shaped spring 30, which is placed within theinterior of the cap 21 through a slot 31. The bent mid-portion 32 of thespring is 'lodged in av hole 33 formed in `the wall, of the cap oppositeto the said slot 31, said hole being countersunk upon the inside of thecap to form a suitable seat l'for the said bend. lVhen :'.i positiontlie end 34 of the spring to engage beneath the shown in Fig. 2, and

in position when once inserted. The opposite end of the spring wall ofthe cap, as

held in the `posi-V lies alongside the a' rib 26 yand this merges aboveinto the vProjects slightlyA and is yformed vinto a head 35 whielrprotruds through the slot 31 and a slot 36in v.the clip. A" hook 37engages the wallofthe clip adjacent kthe slot' `36` to hold the clip inplace, as shown in Fig. 2,

a notch 38 .being provided for the insertion of the finger nail, lor asuitable implement, when it is desired to compress the spring tovrelease the clip.

Within the bore 21 ofthe barrel is slidably arrangeda piston/39,furnished with a suitablefpacking ring 4.0'. I prefer to form 'l -thispiston f `hard rubber and make thev ring of Soft rubber to insure aproper lit andinsure an `eifective `action of the piston {wlthoutproducing a friction which would prevent thedevice from workingsmoothly.

This piston is provided with a screw-eye this purpose being as followsThe piston.

`11,which is inserted into an axial hole in lsaid piston, andserves asan attachment forthe hook 'end 28 of the clip 25, by .means of which thepiston is operated to fill the barrel, lthe manner of using it forstands normally near the upper end of the barreljas shown in Fig. 2,'and -when the reservoirv becomes empty of ink, the cap 21 isfremoved,and the clip released by compressing the springv with the linger nail,which ,engages the notch 38. The hook 28 is then made to engage thescrew-eye 41,

and 'to facilitate this procedure, the upper A end of the barrel islfurnished with a mar- ,ginal slot or slit 42,'the special advantage beentirelyfilled below the piston. Disenbeingthatthe' piston can thus bereached whenit is below the upper end ofthe barrel. I-Iavingthus engagedthe screw eye' with vlsaid hook, the piston is then pushed to theybottom ofthe cavity.' The lower end of the barrel is now dipped into theink lsup y ply and' the piston-carefully drawn back -by means oftheengaged clip to the initial position at the upper end of the barrel, the

ink being drawn by way *of the groove 19 into the `reservoir 20, so thatthe latter will gaging the hookfrom the screw eye, the

clip is folded," alongside the cap as before,
